Show original supplier description
The Full Blown Stage 1 Turbo Kit is a comprehensive performance upgrade designed specifically for the Honda Grom MSX125. This kit aims to significantly boost power output, delivering an impressive 15 horsepower increase (a 67% gain) on pump gas without requiring internal engine modifications. Its design allows it to fit seamlessly within the stock bodywork, maintaining a discreet, factory look. The kit includes all necessary components for installation, such as an FBM Spec Turbo, FBM Stainless Up pipe and Downpipe, an FBM Intercooler Kit with couplers and clamps, an FBM CNC Billet Intake adapter, an FBM Oil Feed line, and an FBM Turbo support bracket, along with fittings for the oil feed. Important notes for installation and operation include that the kit does not include a programmer but comes with a basemap tune for pump gas. High-flow injectors are intended for E85 fuel only. Depending on the specific programmer and the bike's year, the O2 bung and Downpipe bracket may require welding. This kit comes with a 2-year warranty on workmanship (such as cracking pipes or fittings), the turbo unit, and the fuel injectors. Please allow 6-8 weeks for shipping and handling.
